Embodiment 1 to 7

[0024] The carbon nanotubes used in the formulations of Examples 1 to 7 are carbon nanotubes with a diameter of 20±5 nm and a length of 1˜10 μm after amination treatment.

[0025] The amination treatment method of carbon nanotubes is as follows:

[0026] First, ultrasonically disperse 100 mg of carbon nanotubes, 5 g of potassium hydroxide, and 100 mL of ethanol together for 30 min, then heat and reflux and stir for 8 h to react, filter the reaction product, wash with ethanol for 3 times and wash with deionized water until the filtrate is neutral, and place in a vacuum Dry under reduced pressure in an oven for 12 hours at 80° C. to obtain hydroxylated carbon nanotubes.

[0027] Then, mix 50mg of hydroxylated carbon nanotubes with 50mL of toluene and ultrasonically disperse for 30min, heat to 80°C while stirring, and add 2ml of toluene solution with a concentration of 5wt% aminosilane dropwise at a rate of 5ml / min, and react at constant temperature for 8h Finally, the reaction ...

Abstract

The invention relates to a composite material of polyphenyl ether / nylon / carbon nano tube and a preparation method thereof. The composite material is characterized by comprising the following components of 43-50% of polyphenyl ether, 35-40% of nylon, 0.4-1.5% of carbon nano tube, 9.5-20% of compatibilizer and 0.1-0.5% of antioxidant. The composite material of polyphenyl ether / nylon / carbon nano tube provided by the invention fully utilizes the characteristics that the carbon nano tube has high draw ratio, large specific surface area and good appetency on a polymer after polar treatment, and after the carbon nano tube is introduced to alloy, the mechanical property and the thermal property of the composite material are greatly improved; the prepared material is high in additional value; the application of the polyphenyl ether / nylon alloy in higher end field is expanded; and the requirements on high-performance materials in the fields such as electronics and electrical, aerospace, national defense and military are met.

Description

technical field [0001] The invention relates to the field of plastic alloys, in particular to a polyphenylene ether / nylon / carbon nanotube composite material and a preparation method thereof. Background technique [0002] Polyphenylene ether is also known as polyphenylene oxide, referred to as PPO or PPE. Polyphenylene ether has a series of excellent properties, which are mainly reflected in several aspects: 1. Small specific gravity, small linear expansion coefficient, and non-toxic. 2. The material has strong rigidity, good wear resistance, low friction coefficient, hard and tough, high mechanical strength and good dimensional stability, and low product molding shrinkage. 3. Excellent chemical properties, low hygroscopicity. 4. Good heat resistance, heat distortion temperature of 190°C, glass transition temperature of 210°C, and decomposition temperature of over 350°C. 5. Excellent flame retardancy, self-extinguishing, only need to add a small amount of flame retardant t...
